The drill team needs to earn $695 so they can buy new flags for a routine. During the summer they can make $5 per hour working at a fireworks stand and $9 washing cars. They are only allowed to spend 107 hours total fundraising. In order for them to work exactly 107 hours and hit their goal exactly, how many hours should the drill team spend at the fireworks stand?

So have two rates, $5/hour and $9/hour and a total of 107 hours to make $695. So here are your variables: x=number of hours at fireworks stand (107-x)=number of hours washing carsso 5 x +9 (107-x)=695 and solve for x 5 x +963 — 9 x=6954 x=268 x=67, so they spend 67 hours at the firework stand.
